CHALK-HOLDER.

Specification of Letters Patent.

Patented July 28,, 1914.

Application filed April 6, 1914. SerialNo. 830,039.

To aZZ whom it may concern:

Be it known that I, NICHOLAS MIGHANEK, a subject of the Emperor of Austria-Hungary, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Challr-Holders, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in chalk holders, and more particularly to that class of chalk holders which are adapted for use in billiard rooms.

An object of this invention is the provision of a chalk holder in which a block of chalk may be securely locked so that the same cannot be removed, whereby the chalk must be entirely worn away by the application of cue tips thereto before another block of chalk can be secured in the holder.

A further object of this invention is the provision of a chalk holder comprlsing a shell having the opening in one end thereof restricted, and a cap for closing the other end of the shell, a spring being connected to the shell for locking the cap thereon, the spring being held in looking engagement with the cap by the periphery of the block ofchalk supported in the shell, so that the cap cannot be removed until the chalk retained in the shell is entirely worn away.

With these and other objects in view, my invention consists in the novel construction, combination, and arrangement ofparts, to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which,

Figure 1 is a vertical section of the holder, showing a block of chalk mounted therein; Fig. 2 is a sectional view on the line 22 of Fig. 1; Fig. 3 is a vertical section of the holder with the block of chalk removed; Fig. 4 is a vertical section of the shell; and Fig. 5 is a view looking at the open end of the cap of the holder.

Referring more particularly to the draw-,

ing, the numeral 1 designates the shell which is designed to encircle a block of chalk 2, the outer edge of the shell being provided with an inwardly extending flange or shoulder 3 which forms a stop for en gagement with the chalk to prevent the same from moving out of the shell. A cap 4 is provided for closing the inner end of the shell, the cap being preferably of a length substantially one hall. of the length of the shell land being provided in its periphery with a crimp 5, the crimped portion of the cap being forced inwardly thereofto form an inwardly extending-rib 6. The cap at is provided with a handle or bail 7 by means of which the holder may be suitably connected to a billiard table or wall. Connected at one end to the inner periphery of the shell adjacent its outer end is a leaf, spring 8, the inner end of the spring being-projected beyond the inner end of the shell, the

projectingportion of the spring being bent outwardly to form a latch 9 for engagement with the rib 6 in the cap.

In thepractical use of my device, the chalk is placedwithin the shell 1 and pushed downwardly to engage the flange or shoulder 3, the block being provided with a longitudinal groove 10 in its periphery which receives the leaf spring 8. It will be seen from the drawing, that the free end of the I spring, 8 is curved inwardly to normally dispose the latch 9 thereof out of alinement' with the rib 6. The chalk 2, when inserted in the shell, is adapted to force the free end of the spring outwardly to dispose the same in alinement with the rib 6 so that when the cap is placed over the inner end ofthe shell, the latch of the spring engages the rib 6 thereby locking the cap and shell together. It will be seen that the engage ment of the spring 8 within the groove 10 in the block of chalk prevents the chalk from rotating relativelyto the shell when a one tip is applied to the chalk and twisted thereagainst. It will also be readily understood that the inward tension of the spring 8 will prevent the chalk from moving longitudinally of the shell when the chalk has been worn down considerably. chalk maintained within the shell has been entirely worn away, it will be seen that the free end of the spring will move inwardly so that the latch portion 9 thereof will move out of engagement with the rib 6 on the cap, whereby the cap may be readily separated from the shell and a new block of chalk may be placed within the shell and the cap replaced thereupon in the same manner.

From the abovedescription, taken in connection with the accompanying drawing, it will be seen that I have provided a chalk holder from which accidental disengagement of the chalk is impossiblewithout breaking of the chalk, as the periphery of the block engages the locking spring and maintains After the the same in looking engagement with the rib on the cap.

While the accompanying drawing illustrates the shell as cylindrical, it will be readily understood that the shell may be angular in construction to receive an angular block of chalk, the various parts of the device being equally eflective regardless of the conformation of the shell.

Having thus fully described my invention, what I desire to secure and claim by Letters Patent, is

1. A chalk holder comprising a shell having an inwardly extending flange at one end, a cap mounted upon the opposite end of said shell, said cap having an inwardly extending rib formed thereon, a leaf spring connected at one end within said shell, and the opposite end of said spring projecting from the shell for engagement with the rib on said cap, as and for the purpose de scribed.

2. A chalk holder comprising a shell having an inwardly extending flange at its outer end, a cap for engagement with the inner end of said shell to close the same, said cap having an inwardly extending rib formed thereon, a leaf spring connected at one end to the inner periphery of said shell adjacent its outer end, the free end of said spring projecting beyond the inner end of said shell, the free end of said spring being curved so that the same is normally spaced from the inner periphery of said shell, the

projecting portion of said spring being curved to form a latch, the latch being normally disposed out of longitudinal alinement with said rib, said latch being moved inwardly upon application of the chalk within the shell, whereby the latch is securely locked in engagement with the rib on said cap.

3. The combination with a block of chalk having a longitudinal groove in its periphery, of a holder comprising a shell having an inwardly extending flange at one end, said shell being adapted to receive the chalk, a cap for closing the opposite end of said shell, said cap having an inwardly extending rib formed thereon, a leaf spring connected at one end to the inner periphery of said shell adjacent its inner end, the body of said spring engaging the groove in the periphery of said chalk and the opposite end of said spring projecting within said cap for engagement within said rib, as and for the purpose described.

In testimony whereof I hereunto afllx my signature in the Presence of two witnesses.
